' Application Med January 26, 1984. Serial No. 688,898.

, This invention relates to. improvements in automaticwindshield cleaners, and more particularly to means of mounting the same.

One object of the inventionis to' rovide 5. a' structure wherein the fluid actuate motor Fig. 1 is ave'rtical fore-and-aft sectional-v view showing the automatic --windshield cleaner of the fluidactuated type combined with one of the frame members of the wind-' shield and the combined structure operatively mounted on said shield.

Fig. 2 is a front elevation of the -structure shown in Fig. 1.

As above pointed out, it is contemplated,

1present invention, to combine the windshie d cleaning apparatus with the frame of the windshield in such the carrier 19 will. diver downwardly from the windshield glass. a cylinder 1s con-1 nected through suitable'conduits with a par tial vacuum or and automatic va ve mechanism,,not shown, .6 is provided for controlling the fluid flow soas to produce the desired operation. -S u orted in any'suitable manner from the sli e lock .19 is a .wi er arm .21- carryingat its lower end the w1per element 22. which one gages the lass of the windshield in theusual manner. y e front portion of. the top of the vehicle is shown at 23. "The'pulleys 18- are readily accessible by removing the end;

caps 14.- 7e

.- I n macs a is preferred to answer the cylin that the housing element for the movable member of the fluid actuated motor forms a 9 part (integral or otherwise) of said frame.

11' Figs. 1 and 2 one embodiment of such a structure or combination is illustrated,

/ wherein the windshield is shownat 10, and

is provided with top and side frame mem- 85 bers 11 and 12, respectively. .In' these figures the top frame member .11 is constructed as an integral part of the cylinder 13 of the fluid actuated motor havingend caps 14. This particular motor forms the subje'ct-matter of my co-pending application filed January'26, 1924, Serial No; 688,892,.

and is shown herein merely for illustrative.

purposes. Briefly stated, it vcomprises the statlonary outer'cylinder 13, dpreviously-mentioned, in which is mounte a recipro'cable I piston 15. Cables 16 and 17 are attached 'to the opposite faces ofthe piston and 'extend over suitable pulleys 18 at opposite ends of the cylinder and, exteriorl thereof to a slide block 19 carried in guide-ways 20 beneath said cylinder. Theflanges forming the guide 20 as well as those orming the grooves to receive theglass are preferably formed integral witlr the cylinder 13 and are substantially radial of the cylinder so that a' pair of flanges f0 a ceive the edge of thefifish cylinder also having on itspenphery'and er '13 of the motor of 21- ion h substantially co-extensive with the widt of the shield so that no 0 11 spaces willbe left at either end thereo intermediate the windshield and the vehicle top. f j I The movable element of the motor (piston or cylinder) is housed within the top frame member of the windshield or a part thereof, and is combined therewith in such wise as to form. a unitary structure, the cylinderv ofv the motor forminga part of the top*frame. member.

Obviously, the invention is s'usce tible of changes and modifications without eparting from the spirit thereof, and it is not therefore desired to limit the same exceptwhere; limitations appear in the appended claims. -WhatIc1aim is:

1. A combined windshield and cleaner construction, com(jiprising a cleaner motor including a cylin er and a piston operable therein, thecylinder having on its perlphery a pair of ,-flanges forming a groove to rece ve the edge of the windshield glass, sald cylinder also havin on its perlphery and forwardly of sai flanges a guide extendm substantially parallel to said lengthwise of the cylinder, a wiper carrier operable by the piston and slldable along the guide on the exterior of the cyhnder and a wiper element operable by sald carrier. a

'2. A combined windshield and cleaner construction, comprisin'g'a cleaner motor in-. cluding af cylindenand a piston operable therein, the cylinder having on its periphery oovelto red glass, said Oil ressure producing means forwardl of said flanges a second pair of flanges efining a guideway, said formed g ove and guidewa extending radially om the periphery o the cylinder and being relativel diver ent therefrom, a carrier slidable in t e guid way and having a part extending radiall from the c linder and away from the p ane of a win shield glass when engaged in the groove, and a wiper arm resiliently carried on the outer end of said carrier art.

3. A com ined windshield and cleaner construction, compr'isin .a cleaner motor including a cylinder an a piston operable therein, the cylinder having on its periphery a pair of flan forming a groove toreceive the edge of e windshield glass, said cylinder also having on its periphery and forwardly of said flanges a guideway, a carrier slidable in the guidewa pulleys mounted adjacent the 0p osite en 5 of the cylinder .With their axes su tantiall at right angles to the radially plane exten ing through the guideway, whereby said pulleys will be inclined from the groove, and a cable extending from the opposite sides of the piston through the ends of cylinder and taking over the pulleys for connecting the piston to said carrier.

In testimon whereof, I have hereunto set mfy hand at hicago, Illinois, this 14th day 0 January, 1924.
